I'm a pats fan but I'll leave my thoughts here. I had no real vested interest in the Skins/ Hawks game, but from my standpoint and I mentioned this to my buddy at half, as a coach how do you not put Cousins in? RGIII clearly could not move, the potential for him to run was eliminated, eliminating the read option. He couldn't throw off his back foot, so he had no downfield power or accuracy.
I understand he is your franchise QB and he may have not wanted to come out of the game, but you are trying to win a playoff game, and you risk further injury (as seen) by leaving him in. From my view it was the wrong call
But on another note a great win from the Hawks, great comeback and to me the Falcons need to watch themselves, they are on a roll right now.
